STOPCOCK OB VALVE.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed October 24, 1919. Serial No. 332,875.

To all whom it may concern:

Be it known that 'we, BENJAMIN BUTLER and WILFRED BUTLER, subjects ofthe King of Great Britain and Ireland, residing at Dukinfield, in thecounty of Chester, England, have invented new and useful Improvements inand Connected with Stopcocks or Valves,.of which the following is aspecification;

' tically movable threaded barrel, nut or sleeve which accurately fitsand is guided by the upper part or half of the valve casing. Thisthreaded barrel, nut or sleeve carries means which, while allowing thesame to move up or down; prevent rotation and also carries or supports aface or surface which when the valve is fully open, beds on a surfaceand helps-to pack the threaded barrel, nut, or sleeve, and so augmentsthe action of the packing about the operating spindle. The verticallymovable threaded barrel, nut or sleeve carries or has connected to it, avalve or clack, and such valve or clack may be free .to rotate oraccommodate itself to the .valve seat. The

valve seat may be formed in the lower half or body of the valve, or samemay be a separately applied valve seat, as shown, having a conical ortapered'portion fitting a corresponding tapered portion of the di-.

vision web, the valve seat being screwed into position or held by theaction of a screw thread. Tool holes are provided for applying andremoving the valve seat. -Any other form of valve seat may be usedeither formed in the division web or otherwise or separately applied. p

In order to better indicate the nature of our invention we will describeby reference to the attached drawinga suitable construction of valve inaccordance with our invention.

LIn the said drawing Figure 1 shows a vertical section of a type ofvalve embodying the features of novelty.

F 2 is a section on the line 11, Fig. 1. Fig. 2 shows a plan view of thedetachable valve seat.

Fig. {l is an elevation showing the movable threaded barrel separately,the view being taken at right angles to the line 14, Fig. 2. Fig. 5 isaninverted lan view of Fig. 4. Fig. 6 shows a form 0? movable valvecarrier which engages and is actuated by the movable barrel seen in Fig.4.

We make use of a suitable operating spindle such as a and this is formedwith or I carries a plain collar 0', while the lowenportion is screwthreaded as at a The collar is ground on or fits a shoulder in the boredupper part b of the valve body, and works thereon. The spindle is packedby a ring of packing a and a gland a made 1n one, two or more parts andoperated by a nut a. As thus constructed, the packed operating spindle acan rotate but does not move up or down. The lower screw-threadedportion of therotatable spindle fits in a threaded barrel, nut, orsleeve, such as the barrel 1) which device is accurately turned 1 and'isfree to slide up and down in a bored cavity in the up er half or bodycasting b of the valve. I rejections or lugs 6 b? from the threadedbarrel, nut, or sleeve, engage vertical grooves or channels 6 6 cut inthe upper half or bod of the valve (see Fig. 2). The purpose 0 theprojections or lugs b 6 is to prevent the threaded barrel,

, nut, or sleeve (2, from rotating while not interferingwith the up anddown movement. Any otherequival ent arrangement may be used for thispurpose. Said threaded barrel, nut, or'sleeve b by preference alsocarries 01'- supports an annular flange b which, when the valve is fullyopened, beds against a seat b formed in the upper half or castingcarrying the valve spindle and adjuncts. Such annular. flange works inan enlarged opening concentric with the bore of the upper part of thevalve body .and conveniently of larger diameter than the threadedbarrel, nut, or sleeve. The actual valve itself ma be attached toorcarried by the serves as a guiding and ourselves.

lace.

and we in no way restrict screwed into greatly varle annular flange onor in connection with the threaded barrel, nut, or sleeve, in a measureacking means. Thus we get as it were a-triple guided and triple packedvalve of very simple and d11- rable construction. 0

Slight variations may be necessary in accordance with the particulartype of valve to which our improvements are applied.

It is obvious that the gland employed and the construction may be suchas not to require the introduction of a packing to pack the spindle, asfor example, we may depend on ground faces or parts and so make thevalve packingless.

What We claim is.

1. A stop valve, comprising an upper body portion and a lower bodpdrtion detachably securedtogether, said upper body portion having alongitudinal bore therein, said bore being of larger diameter at theupper portion than at the lower portion thereof.

thereby to form a shoulder in said bore, a spindle rotatable in saidbore and having secured thereto a collar seated on said shoulder, said sindle being exteriorly threaded below sald collar, a gland for retainingsaid collar on its seat, said bore having in its side wall a pair ofoppositely disposed longitudinall extending guide grooves, an interiorlyt readed-barrel member engaging the threaded portion of the s indle andhaving a pair of guide lugs slid alile in said grooves, said up er bodpor tion having at its lower en opening concentric with its bore, anannular flange carried by said barrel member and operating within saidenlarged opening, and a valve removably supported by said barrel at itslower end, the lower body portion be ing provided with a dividing webhaving an opening therein, and a removable valve seat secured in saidopening for cooperation with said valve.

2. A stop valve, compri ing an upper The detachable valve seat has 4thereof thereby an en arged ne'rofsvs body portion and a lower bodportion detachably secured together, sai upper body.
